We have seen a lot of that here in Derbyshire over the last year. One person told me that it was caused by a special aphid that attacks conifers. I don't know if that is true. Every tree that has been affected here has been dug out but I don't know if that was entirely necessary or not. From the extent of the damage, I would say it probably was a pragmatic approach to the problem.

A lot of phytophthora about now and in recent years. I have lost a juniper, photinia and neighbour has conifers in his hedge dying. Nothing you can do to save them. Could you put a feature there.....maybe a mirror or maybe an arbour?
